It’s probably worth giving you the link to Max McLean’s readings of both this chapter and also John 1.
Rom 1:1 Paul, a servant of Jesus Christ, called to be an apostle, separated unto the gospel of God,
Rom 1:9 For God is my witness, whom I serve with my spirit in the gospel of his Son, that without ceasing I make mention of you always in my prayers;
Rom 1:15 So, as much as in me is, I am ready to preach the gospel to you that are at Rome also.
Rom 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
That’s a great verse and I love how the KJV unlike the modern versions actually says who’s gospel this is. Not just any gospel.
Also as we begin to look at Jesus’ attraction which will precipitate in the call to “Come and See”, we note these two verses here:
Rom 1:6 Among whom are ye also the called of Jesus Christ:
Rom 1:7 To all that be in Rome, beloved of God, called to be saints: Grace to you and peace from God our Father, and the Lord Jesus Christ.
The WCF has a great chapter on the effectual call…
